Definitions

  • the invention relates generally to a method of grinding a parting/grooving insert, a parting/grooving insert and a slot milling disc.
  • Parting/grooving inserts may be used in turning applications where there is a need for grooves to be made in the work piece, or for cutting off one part of the work piece from another. They may also be used in slot milling applications, for milling slots or grooves by a rotating slot mill.
  • Such a parting/grooving insert comprises a rake surface, a main clearance surface, and a main cutting edge formed between the rake surface and the main clearance surface.
  • the parting/grooving insert comprises a left and a right side clearance surface, wherein the cutting edge comprises a left side cutting edge formed between the rake surface and the left side clearance surface, and a right side cutting edge formed between the rake surface and the right side clearance surface.
  • Fig. 1 a grinding method used in prior art is illustrated.
  • a grinding surface is provided on an outer curved radial surface of a grinding wheel, and the main clearance surface is grinded by placing the insert towards this radially outer curved grinding surface and the parting/grooving insert is moved up and down relative to the curved grinding surface to obtain a flat or plane main clearance surface and a straight main cutting edge.
  • the parting/grooving insert is oriented and positioned in relation to the grinding wheel to be able to grind the left and/or right side clearance surface.
  • An object of the present invention is to provide an improved method of grinding a parting/grooving insert.
  • a grinding method which improves the flatness of the clearance surfaces, as well as the quality of the cutting edge and which may be used to shorten processing times in the process of grinding the parting/grooving insert.
  • the invention relates to a method of grinding a parting/grooving insert according to claim 1.
  • a parting/grooving insert is provided with a planar main clearance surface and a high cutting edge quality.
  • edge quality it is not only important to obtain the right/desired macro-geometrical shape on the main cutting edge, which in this case means that the main cutting edge should be as straight as possible, but also to obtain the right/desired micro-geometrical shape by achieving the right/desired size on edge rounding or so called ER on the main cutting edge.
  • the grinding method provides an efficient way of obtaining both a straight main cutting edge and on a microscopic level a desired main cutting edge rounding.
  • the grinding method in accordance with the invention provides longer engagement between the main clearance surface and plane grinding surface making it possible to reduce the grinding pressure applied to the main clearance surface. This also reduces the pressure on the main cutting edge and the tendency of chipping the main cutting edge. Higher edge quality is hereby achieved, which improves both the cutting performance/machining result and the life time of the insert. Also the processing time of the grinding process may be shortened, because the insert can remain in one position in relation to the grinding wheel (e.g.

  • the left and right side clearance surfaces may also be grinded by tilting the parting/grooving insert from the position of grinding the main clearance surface, minimizing the movement of the parting/grooving insert between the grinding positions and thus shortening the processing time of grinding the insert.
  • the parting/grooving insert may comprise a left hand corner radius surface between the main clearance surface and the left side clearance surface, and a right hand corner radius surface between the main clearance surface and the right side clearance surface, and wherein the parting/grooving insert is gradually moved between the position of grinding the left side clearance surface and the main clearance surface thus grinding the left hand corner radius surface, and/or wherein the parting/grooving insert is gradually moved between the position of grinding the right side clearance surface and the main clearance surface thus grinding the right hand corner radius surface.
